Does anybody have any information on what kind of music they play in the discos on Carnival? I am particularly interested in the newer ships, like the Triumph or the Victory ... is it techno, or Top 40, or a mix of oldies, etc.? Is it pretty much the same every night or do they have different nights? What about in other lounges/areas?

I have been on a lot of cruises on a lot of different ships and have always found the music in the Disco to be a mix. You can also talk to the DeeJay if you have specific requests, and I have never known one not to oblige. As for the other lounges, it will depend on the age group they cater to. For instance, on the S/S Norway, you can always count on slow dancing, Big Band music in the Club Internationale. In the Sports Bar, you will find anything from 60s pop to C&W, and if you want the rest, from Britney, N'Sync to Rap, etc. head down to the Disco. I know you didn't ask about the Norway specifically, but I am just using that as an example.
